Dozens of people are trapped after a five-storey building collapsed in the Indian city of Mumbai.

Rescuers are trying to reach around 25 people under the building in India's financial capital.

There have been no immediate reports of casualties following the collapse of the residential building shortly after dawn.

It was the second large building in Mumbai to fall down this year. In June, at least 10 people died when a three-storey building collapsed.

Across India, building collapses have become relatively common.

Massive demand for housing around India's fast-growing cities combined with pervasive corruption often result in builders using substandard materials or adding unauthorised floors.
